Application filed Hay 6, 1907. Serial No. 372,126.

To all whom 'it may concern:

'Be it known that I, VINCENT C. DE YEAR nonno, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and luseful Improvements in Telegraphic Sounders, of which the following is aspecification.

This invention relates to a sounder for telegraph systems, and it relates more particularly to anv attachment that is adapted to be substituted for the gong of an electric bell, whereby the hammer can be used for. giving the sounds.

The invention has forl one of its objects to improve and simplify the construction of devices of this character so as to be easy and inexpensive to manufacture, readily applied to an ordinary electric bell, and thoroughly satisfactory in service.

A further object of the invention is the provision of an attachment that is adapted to be applied tothe baseplate of the elec- -tric bell outfit in such position that the hammer can strike against the same for pro'- ducing the soundsY for receiving a message, thus enabling a simple form of bell to be converted into a telegraphic sounder.

Vith these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel. features of construction and arrangement of parts which will be hereinafter more fully described arid set forth with particularity in the claims appended hereto. i

In the accompanying drawing, which illustrates one of the embodiments of the in vention, Figure l is a plan view of an electric bell with the casing removed and the attachment in section, and showing the elec- Fig. 2 is a sectionof the hammeron the bell strikes. Fig. 3 is a plan view lof the attachment.

Similar reference characters are employed to designate corresponding parts" throughout the several views.A

Referring-to the drawing, 1` designates the with respect to the 'attachment so'` as to bring the hammer 5 in proper relation tothe latter. The attachment or member 8 against which the hammer strikes comprises a strip of brass or other suitable material that is bent into the general form of a U, with the extremities of theI arms 9 apertured for receiving a boltlO, whereby the arms can be adjusted to or from the hammer 5. The bottom of the U-shaped member is provided with an aperture 11 for receiving a .screw l2, whereby the member is attached to the basel.

In connecting the device in an electric circuit for receiving messages, the binding post I3 alone is employed and this post is connected with the electro-magnets 3 on one side by the conductor I'f with the ordinary Morse key I5 on the other sideand from the `Morse key extends a conductor 16 connected with a battery I7, the negative side of the battery being connected by a conductor 18 with the post 19 that usually carries a platinum pointed screw when the mechanism is connected up for ringing as a bell. screw is dispensed with in the present instance and the conductor I8 is soldered or otherwise suitably secured to the member I9, the latter being also connected with the electro magnets in the usual manner. By manipulating the key l5, the circuit can be opened and closed, thereby energizing the electro-magnets and causing the armature to operate as an ordinary sounder by striking the sounding member or attachment 8.

It will thus be seen that a very simple and thereof, I desire to have it understood that the apparatus shown is merely illustrative.

and that such changes may be made when desired, as are within the scope of the claims.
